  1. Species composition and health risk assessment of arsenic in Agaricus blazei Murrill and Tricholoma matsutake from Yunnan Province, China

    • Sat, 11/05/2022 - 04:00
    • Journal of Food Composition and Analysis
    • High concentrations of total arsenic (As) has been found in Agaricus blazei Murrill and Tricholoma matsutake samples. It is important to study the As species in A. blazei and T. matsutake for accurate health risk assessment. Total As was measured by inductively coupled plasma-mass spectrometry (ICP-MS). An analytical method was developed to determine As species in mushroom by using anion exchange and cation exchange chromatography coupled to ICP-MS.

  3. Biocontrol of strawberry gray mold caused by Botrytis cinerea with the termite associated Streptomyces sp. sdu1201 and actinomycin D

    • Fri, 11/04/2022 - 04:00
    • Frontiers in Microbiology
    • Strawberry gray mold caused by Botrytis cinerea is one of the most severe diseases in pre- and post-harvest periods. Although fungicides have been an effective way to control this disease, they can cause serious “3R” problems (Resistance, Resurgence and Residue). In this study, Streptomyces sp. sdu1201 isolated from the hindgut of the fungus-growing termite Odontotermes formosanus revealed significant antifungal activity against B. cinerea.

    • Antibiotics
    • Fluoroquinolones (FQs) are among the antibiotics whose widespread use in farm-raised animals results in potentially harmful residues in the end products. Additionally, most Thai farmers use antibiotics. Amoxicillin and enrofloxacin were commonly used by pig farms, and hens were given enrofloxacin to prevent immunization side effects. Moreover, antibiotic overuse has harmed food safety in the long term, and the use of low-dose antibiotics causes bacterial resistance.
